Objective:To study the action of SH in mid-term cornea preservation.Methods:SH was added into mid-term preservation solution(MMK) to make the new storage media with SH of three different concentration (0.05%,0.03%,0.01%).The contrast group was MMK medium without SH.The corneal appearance,transparence and ultrastructure were observed,and trypan blue-alizarin red staining of CEC,SDH and G-6-P enzyme staining with histochemistry were made in different storage time.Results:The transparence of cornea and ultrastructure of CEC in all the experimental groups were better than that of the contrast.The activity degree of CEC was highest in group I,lowest in the contrast,and statistically significant among all the groups.Conclusion:SH plays an important role in protecting CEC in middle storage medium,and enhances the quality and prolongs the duration of the preserved corneas.The protective effect is determined by the consistence of SH.

Objective To analyze the risk factors of ANCA-associated systemic vasculitis with pulmonary infection to improve the alertness of clinicians to imprave the survival of patients.Methods Seventyfive AASV patients in Shanghai Renji Hospital from January 2010 to June 2013 were selected,and logistic regression models was applied to analyze the correlation.Results Of 75 AASV patients,39 (52％) cases were males,36(48％) cases were females,the average ages were (56±19),56(75％) cases were MPA,17(23％) cases were WG and 2(3％) cases were CSS.42(56％) cases were diagnosed to have pulmonary infection.Among the patients with pulmonary infection,23 (55％) were males,19 (45％) were females,24 (57％) were older than 60 years old,17(12％) had WG,37(88％) had MPA,and 8(19％) died.Meanwhile,11(26％) had bacterial infection,2(5％) had tuberculosis,2(5％) had fungi infection,and 27(64％) had mixed infections respectively.8(19％) cases died.Multivariate logistic regression analysis showed that those who were older than 60 years (OR=15.13,95％CI 2.16-106.04,P＜0.01),who were diagnosed as MPA (OR=9.00,95％CI 1.37-59.14,P＜0.05),who had hypoproteinemia (OR=17.61,95％CI 3.14-98.74,P＜0.01) and interstitial lung disease (OR=11.83,95％CI 2.19-63.85,P＜0.01) were more likely to complicate with pulmonary infection.Conclusion Those who are elders,diagnosed as MPA,with hypoproteinemia and interstitial lung disease have higher risk to have pulmonary infection among AASV patients,which underscores that clinicians should pay more attention to this complication of AAV patients.

Objective To study the dilution model of the early pregnancy test strip for the quantitative detection of serumβ-hu-man chorionic gonadotropin(β-hCG)level by the Abbot AxSYM detection system and its application.Methods The detection re-sults of serumβ-hCG level in 5 612 outpatients and inpatients of the internal medicine department and the gynecology and obstetrics department during 5 years were retrospectively analyzed.In addtion,234 serum samples from the patients were collected for prelimi-narily determining the serumβ-hCG level by the early regnancy test strip and then the quantitative detection of serumβ-hCG level was detected by the Abbot AxSYM detection system.Results The retrospective analysis showed that 241 cases(4.6%)were low-age pregnant women.The qualitative screening was necessary.The screening model was successfully established.But one thing to note was that the part of serum sample needed to be taken out and put into another tube for determination.Conclusion Establishing the rational and effective dilution interpretation model of early pregnancy test strip for screening serumβ-hCG can bring the econom-ic and time benifits for the routine detection work of the Abbot AxSYM detection system.

Objective To analyze the concentration changes of serum hypoxia stress peptide (HSP)and plasma nitrogen monoxidum(NO)in the entering mountain rapidly man and to explore the importance of HSP and NO in adaptation of man to altitude hypoxia.Methods The levels of serum HSP and plasma NO2-/NO3-were measured from 106 entering mountain rapidly men,105 altitude in habitant,105 altitude immigrant and 104 plain healthy controls,respectively by chromatometry and NO2-/NO3-reagent.Furthermore,the content of serum HSP was determined in 106 entering mountain rapidly men,respectively at the time of 24 h,48 h,76 h,l week and 1 month after entering mountain.Results The level of serum HSP was significantly higher in entering mountain rapidly men than in habitant,immigrant and plain controls(P＜0.05),while there was no statistical difference between in habitant,immigrant and plain controls(P＞0.05).At 24h after entering mountain rapidly,the level of serum HSP was significantly increased and reached the peak.At 48h and 76h,it was slightly decreased,but still maintained a high level.At 1 week and 1 month,it gradually and significantly went down,but was still significantly higher than that in plain controls.Similarly,the level of plasma NO2-/NO3-was significantly elevated in entering mountain rapidly man,compared with inhabitant,immigrant and plain controls(P＜0.05).It was lower in inhabitants and immigrants than plain controls,but the difference was not statistically significant(P＞0.05).Conclusion The present results demonstrated that the levels of serum HSP and plasma NO were significantly up-regulated in healthy adults after en tcring mountain rapidly in order to adapt to altitude stress,and restored gradually to the normal level as time went by.

Objective The quantitation measurement of microalbuminuria was adopted to verify the feasibility of urinary microalbumin and ratio of mieroalbumin to creatinine (M/C) detection with dry hemieal method. Methods Totally 80 urine samples from the patients with clinically diagnosed dia-betes were tested by the immune quantitation method (immunoturhidimetric assay) and dry heroical method (HT2000 urine analyzer and test paper, Guilin Hnatong Company) simultaneously. Sarcosine oxidase method was applied to measuring creatinine level. Ten cases of outliers were removed. With the quantitation result of M/C as the reference standard, immune quatilyzation of the M/C as refer-ence, we compared and analyzed the results of the immune quantilization of urine microalbumin, those of the dry chemistry method and of the dry chemistry system detecting M/C. Results There was sig-nificant differences in test results of urinary microalbumin with the dry chemistry method and the im-mune quantitation method (P<0.01) The sensitivity, accuracy and Youden index of the microalbu-minuria testing had been observed to decrease in order in immune the dry chemistry method, the im-mune quantitation method and M/C quantitation detection method. Conclusion The sensitivity of semi-quantitation dry chemical method is satisfactory in detecting microalbumin, which may be used as a means of microalbumin screening. M/C detection with the dry chemical method isn't suitable for screening microalbumin in instant urine samples.

N 6-methyladenine (m 6A) is the most abundant internal RNA modification found in a variety of eukaryotic messenger RNAs and long non-coding RNAs, which is dynamically regulated by m 6A methyltransferases and demethylases, and mainly works after recognized by m 6A binding proteins. m 6A is involved in almost every step of the RNA life cycle, including RNA transcription, splicing, localization, nuclear transport, translation, and degradation. Disorder of m 6A modification can lead to RNA dysfunction and abnormal gene expression. m 6A modification regulators express abnormally in various cancers, and play an important role in cancer formation, proliferation, differentiation, invasion and metastasis.

Objective: To observe the effect of paroxetine on the levels of serum interleukin-1 beta (IL-1β) and IL-6 in patients with early poststroke depression (PSD) and the degree of improvement of the depressive symptoms. Methods: Two hundred twenty-three consecutive patients with stroke within 72 hours of symptom onset were included. A total of 42 patients with early PSD whose Hamilton Depression Scale (HAMD) score ≥ 8 within 72 hours of onset were selected. They were randomly allocated into paroxetine treatment group (n = 20) and control group (n = 22). The patients in the treatment group were treated with paroxetine 20 mg/d at the time point of 72 hours, and the course of treatment was ≥ 3 months. The other treatments were the same in both groups. The serum concentrations of IL-1β and IL-6 at 72 hours, 1 and 3 months after onset, as well as the HAMD scores at all time points were compared. Results: Circled digit oneThere was no difference in the HAMD scores between the 2 groups at 72 hours after onset. The HAMD score in the treatment group was lower than that in the control group at the same time period 1 and 3 months after treatment. There were significant difference (P < 0.01). There was no significant difference in the HAMD scores between the 2 groups 1 and 3 months after treatment. Circled digit twoThere was no significant difference in serum IL-1β and IL-6 at 72 hours after onset in both groups of patients. The IL-1β and IL-6 in the treatment group were lower than those in the control group at the same time 1 and 3 months after treatment. There were significant difference (P < 0.01). IL-1β and IL-6 reached the peaks at 1 month after treatment in both groups, and began to decrease at 3 months, but the control group was still higher than the level at 72 hours (P < 0.01), and the treatment group was decreased to the level at 72 hours. Conclusion: The increased serum IL-1β and IL-6 concentrations may be ralated to the onset of patients with early PSD. Paroxetine may improve the depressive symptoms of patients by the interference of the serum IL-1β and IL-6.
